Janet bought same bars of choclate to share equally with her friends. she bought between 35 and 50 bars altogether. if she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over. If she shares the bars equally with 6 friends she will have 5 bars left over. How many bars of chocolate did she buy?
a.47
b.45
c.46
d.48
For the conditions to be fulfilled number of chocolate bars Janet bought is 35.
What is an equation?An equation is a statement in form of numbers and variables that both sides are equal.
Janet bought the same bars of chocolate to share equally with her friends and it is between 36 and 50.
There are two possible cases,
Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'A'.
(i) If she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over,
∴ N = 7A + 7...(i).
(ii) If she shares the bars equally with 6 friends she will have 5 bars left over,
Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'B'.
∴ N = 6B + 5...(ii)
Now, we have to equate these two equations,
7A + 7 = 6B + 5.
7A = 6B - 2.
A = (6B - 2)/7.
From here we have to find such integer value of B which also makes the value of A an integer and also when we put the values of either A or B in our equations it should lie between 35 and 50.
So,
A = (6B - 2)/7.
When B = 5 then A = 4. Or when B = 12 the A = 10.
But the B = 12 and A = 10 is inadmissible.
Now, we'll put the value of A or B in eqn (i) or (ii).
Which results in N = 35.
So, the number of chocolate bars she bought is 35.

Step-by-step explanation:
(5x+6) over 2 = 3 (4x+12)
x= -66/19
Multiply 2 on both sides:
2*(5x+6)/2=3(4x+12)*2
Simplify:
5x+6=24x+72
Subtract 6 from both sides:
5x+6-6=24x+72-6
Simplify:
5x=24x+66
Subtract 24x from both sides:
5x-24x=24x+66-24x
Simplify:
-19x=66
Divide both sides by -19
-19x/-19=66/-19
Simplify:
x= -66/19

Step-by-step explanation:
The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x + 4 represent the third integer.
Which equation can be used to find the first integer?
3x + 126 = 2x + 6
3x + 6 = 126
2x + 6 = 126
3x = 2x + 6
Answer:
3x + 6 = 126
Step-by-step explanation:
If you add all of them
x + x+2 + x+4 = 126
simplify the left-side
3x+6=126
subtract 6 from both sides and you get
3x = 120
divide both sides by 3
x=4
Sheila is going to the arcade with only 15 dollars to spend. The cost of each game is 75 cents and the price of admission into the arcade is 5 dollars. Which inequality can be used to solve for g, the number of games that she can play, and what is the maximum number of games she can play?
A - 5g + 0.75 <_ 15, 13 games
B - 0.75g + 5 <_ 15, 14 games
C - 0.75g + 5 <_ 15, 13 games
D - 5g + 0.75 <_ 15, 14 games
Answer:
C
Step-by-step explanation:
It is 75 cents a game plus 5 dollars admission. You should automatically subtract 5 dollars for admissions. That would give you ten dollars. You would just multiply how many games by how much they cost.
(You can also find the number of games first, and then solve the two inequalities that match that number backwards)

The results of a recent survey indicate that the average new car costs $23,000 with a standard deviation on $3,500. The prices of the car are normally distributed. a. If someone buys a car for $32,000, what proportion of cars cost an equal amount or more than this? b. If someone buys a car for $16,000, what proportion of cars cost an equal amount or more than this?
Answer:
(a) 0.0051
(b) 0.9773
Step-by-step explanation:
Let X = prices of the car.
It is provided that [tex]X\sim N(23,000, 3,500^{2})[/tex].
(a)
Compute the value of P (X ≥ 32000) as follows:
[tex]P(X\geq 32000)=P(\frac{X-\mu}{\sigma}>\frac{32000-23000}{3500})[/tex]
[tex]=P(Z>2.57)\\=1-P(Z<2.57)\\=1-0.99492\\=0.00508\\\approx 0.0051[/tex]
Thus, the proportion of cars cost an equal amount or more than $32,000 is 0.0051.
(b)
Compute the value of P (X ≥ 16000) as follows:
[tex]P(X\geq 16000)=P(\frac{X-\mu}{\sigma}>\frac{16000-23000}{3500})[/tex]
[tex]=P(Z>-2)\\=P(Z<2)\\=0.97725\\\approx 0.9773[/tex]
Thus, the proportion of cars cost an equal amount or more than $16,000 is 0.9773.

what is bigger 3.14 or 3.1 repeating
Answer:
3.14
Step-by-step explanation:
compare 3.4 to 3.111111111111111111...
4 is bigger than 1
3.14 is bigger than 3.1 repeating.
The number 3.1 repeating (or 3.1 with an infinite number of decimal places of 1) is equivalent to the mathematical concept of the number 3.1111..., where the digit 1 repeats indefinitely.
When comparing 3.14 and 3.1 repeating, we can consider the decimal places:
3.14 has a hundredth place digit of 4, which is greater than the repeating decimal of 3.1, where the hundredth place digit is 1.
Therefore, 3.14 is bigger than 3.1 repeating.
